Fred and Friends Port a Pint Folding Beer Glass

Bring your personal drinking cup wherever you go in the form of the Port a Pint Folding Beer Glass. It retracts into a small coaster when not in use and extends to a functional cup in a flick of a wrist. The cup is made of hi density plastic material and is very easy to clean. Now drinking your beer can always be in a glass even if there are no cups around.
